一般现在时态
需要掌握五个要点
第一：一般现在时态概念
第二：句子核心结构
第三：时间状语（暗示词/提示词）
第四：动词第三人称变化形式
第五：不同题型的命题意图
一般现在时态概念和结构：
概念：表示现在的状态、经常的或习惯性的动作、表示主语具备的性格和能力等。
核心结构：就是动词原形或三单形式
提示词/暗示词：（常规概念是时间状语）
always总是，一直, usually通常，often经常, sometimes有时, seldom很少，never从不， every day/ week/year 每天/周/年等．
动词“三单”的变化规则如下:
一般动词在词尾加-s,如: helps, makes, gets, swims, knows, plays等.
以s, x, ch, sh, 或o结尾的动词在词尾加-es,如dresses,fixes washes, catches, does goes 等.
以辅音字母+y结尾的动词, 先变y为i,再加-es, 如fly---flies, study--- studies等.
一般不用记，只记2和3
一般现在时态考什么学什么
整体分两类：
动词原型和三单形式
细分为三类：
be动词 ,there be 和实意（义）动词（实意动词原型和三单）
我(I)用am, 你(you)用are,
Is 连着他(he)她(she)它(it),
其它复数都用are.
主语＋am/is/are＋其它成分.
I am a worker.
You are a teacher .
You are very kind.
Tom is from America.
We are in China.
be 动词口诀和例句
用is、 am或 are填空

there be 句型
一：there be 句型基本认识
1、定义：There be句型表示某处存在某物或某人。
2、结构：(1) There is +单数可数名词/不可数名词+ 地点状语.
(2) There are +复数名词+地点状语.
① There is a bird in the tree. 树上有一只鸟。
② There is a teacher and many students in our classroom.
我们教室里有一位老师和许多学生。
③ There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。
留意there be 的就近原则，就近原则的特殊情况和内含some和any句型变化
实意（义）动词的句型
把握一个总的原则：动词变化原型或三单，如果肯定陈述句，碰到人称他她它或对应的三单人称名字，动词需要变三单形式，其它疑问句或否定句都是在此基础上变化（可参考课本语法部分或语法书相关章节）
